Inferring Ecosystem Function from Dissolved Organic Matter Optical Properties: A Critical Review

Environmental Science & Technology, Год журнала: 2022, Номер 56(16), С. 11146 - 11161

Опубликована: Авг. 2, 2022

Over the last 30 years, optical property community has shifted from conducting dissolved organic matter (DOM) measurements on new complex mixtures in natural and engineered systems to furthering ecosystem understanding context of past, present, future carbon (C) cycling regimes. However, appropriate use properties understand DOM behavior biogeochemical is recent debate. This critical review provides an extensive survey literature across atmospheric, marine, terrestrial biospheres using a categorical approach that probes each biosphere its subdivisions. Using this approach, rubric variables, such as productive nature, C rate, inputs, water quality, sets foundation for interpreting commonly used metrics fluorescence index (FI), humification (HIX), specific ultraviolet absorbance at 254 nm (SUVA254). Case studies meta-analysis subdivision found substantial overlap characteristic distributions corresponding FI, HIX, SUVA254, signifying chromophores fluorophores different ecosystems may be more similar than originally thought. challenges researchers consider connectivity when applying results rather making traditional "if this, then that" results-style conclusions.

New insights into carbon mineralization in tropical paddy soil under land use conversion: Coupled roles of soil microbial community, metabolism, and dissolved organic matter chemodiversity

Geoderma, Год журнала: 2023, Номер 432, С. 116393 - 116393

Although the impact of land conversion on carbon mineralization in paddy soils has received increasing attention, coupled roles soil microdiversity and chemodiversity these processes are largely unknown. To address this issue, use from fields (PF) to vegetable (VF), rice-vegetable rotation (RV), abandoned (AL), were investigated study. The relationships between characteristics microbial community, metabolism physiology dissolved organic matter (DOM) analyzed. After conversion, enhanced AL RV, which 217.49% 183.02% that PF. In contrast, no significant change was observed VF, although anaerobic environment transformed into an aerobic one fungal richness/ diversity increased soil. This because directly regulated by DOM quantity labile carbon, indirectly community. Specifically, largest attributed strongest as had DOC contents, hydrophilic substances (e.g., carboxyl, carbohydrate, amino), abundant eutrophic taxa Actinobacteria Proteobacteria). VF mainly related more condensed aromatics oligotrophic microbes, fewer soil, resulting dominance recalcitrant carbon. also prevailed RV. However, RV showed moderate due having proper with high bioavailability. Collectively, results provide molecular insights a micro-chemodiversity perspective, highlights importance nutrient supply strategy.

Microbial Roles in Dissolved Organic Matter Transformation in Full-Scale Wastewater Treatment Processes Revealed by Reactomics and Comparative Genomics

Environmental Science & Technology, Год журнала: 2021, Номер 55(16), С. 11294 - 11307

Опубликована: Авг. 2, 2021

Understanding the degradation of dissolved organic matter (DOM) is vital for optimizing DOM control. However, microbe-mediated transformation during wastewater treatment remains poorly characterized. Here, microbes and along full-scale biotreatment processes were simultaneously characterized using comparative genomics high-resolution mass spectrometry-based reactomics. Biotreatments significantly increased DOM's aromaticity unsaturation due to overproduced lignin polyphenol analogs. was diversified by over five times in richness, with thousands nitrogenous sulfur-containing compounds generated through oxidoreduction, functional group transfer, C–N C–S bond formation. Network analysis demonstrated microbial division labor transformation. their roles determined traits rather than taxa. Specifically, network module hubs exhibited rapid growth potentials broad substrate affinities but deficient xenobiotics-metabolism-associated genes. They mainly correlated liable consumption its recalcitrant compounds. In contrast, connectors peripherals potential degraders slow growth. showed specialized associations fewer molecules probably fed on metabolites hub microbes. Thus, developing technologies (e.g., carriers) selectively enrich peripheral consequently decouple may advance removal.
